14. Open questions
15. Linked fact checks
- All acid-suppressing medicines (PPIs and H2 blockers) are permanently forbidden; heartburn should stop through the diet, not through drugs. – Studies contradicting or limiting the claim
- Reflux (heartburn) and irritable bowel syndrome are largely driven by eating habits; removing white/baladi bread, baked goods and soft drinks can improve symptoms. – Studies contradicting or limiting the claim
- Stopping bread and baked goods for five days will improve 85% of reflux and IBS symptoms within at most ten days; both diseases can be eliminated completely. – Studies contradicting or limiting the claim
- Sleeping or lying down directly after eating is no problem at all; the body is built to eat and drink lying on the side or back. – Studies contradicting or limiting the claim
